BOLSTER FOR LOG-WAGONS.

Speccation of Letters Patent.

Patented Dec. 1d, 1909.

Application led July 11, 1908. Serial No. 443,057.

To all, whom 'it may concern:

Be it known that JOHN T. WTARREN, a citizen of the United States, residing at Hemphill, in the county of Sabine and State of Texas, have invented a new and useful Bolster for Log-lVagons, of which the following is a specification.

The invention relates to improvements in bolsters for log wagons.

The object of the present invention is to improve the construction of holsters for log wagons, and to provide a simple and comparatively inexpensive bolster of great strength and durability, equipped with adjustable chocking devices movable toward and from the center of the bolster to arrange them to accommodate loads of different sizes, and adaptedto be readily dropped below the upper face of the bolster to prevent them from being injured by the logs while loading a wagon, and also to enable a wagon to be readily unloaded.

llllith these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

1n the drawing :-F igure 1 is a perspective view of a bolster, constructed in accordance with this invention. Fig. 2 is an elevation of the same. Fig. 3 is a central longitudinal sectional view. F ig. 4: is a transverse sectional view.

Like numerals of reference designate corresponding parts in all the figures of the drawing.

rThe bolster is provided with metallic sides 1 and 2, spaced apart by a central bearing block 3 and end blocks et to provide opposite longitudinal spaces or ways for the reception of adjustable chocking devices 5. The sides 1 and 2 may consist of one or more pieces and be constructed of any suitable metal, and they are suitably secured to the spacing blocks 3 and 4. lThe central bearing block 8 has a central vertical opening 6' for the reception of a coupling or king pin of the ordinary construction.

The spaced sides of the bolster are provided at their inner faces with vertical bearing recesses 7, arranged at intervals and eX- tending downwardly from the upper edges of the sides 1 and 2. These bearing recesses, which have rounded lower end walls, are adapted to removably receive pivots or journals 8 of the chocking devices 5, whereby the latter are adjustably and pivotally connected with the sides of the bolster. The chocking devices are adapted to be lifted out of the bearing recesses, and their pivots or journals may be placed in any of the recesses to arrange the chocking devices the desired distance from the center of the bolster. 'lhe chocking devices are provided with inclined edges 9 at their upper portions, and they have depending shanks or portions 10, extending into the space between the sides of the bolster and carrying the said pivots or journals S. The inner edges 9, which lit against and receive the logs, extend upwardly and outwardly, and the chocking devices are provided at their outer sides with horizontal shoulders 11, located at a point intermediate of the ends of the chocking devices and above the upper edges of the sides of the bolster, when the chocking device is arranged in operative or engaging position. The outer edges of the upper portions of the chocking devices are preferably vertical, and the said devices are maintained in projecting position with relation to the bolster by transversely disposed supporting plates or members 12, and they are adapted to drop into the longitudinal spaces of the bolster, as illustrated in dotted lines in Fig. 3 of the drawing to arrange them out of the way of the logs when loading or unloading a log wagon.

The supporting plates or members 12, which rest upon the upper edges of the sides of the bolster are adjustable inwardly and outwardly to arrange them in proper position with relation to the chocking devices, and they are provided at one end with spaced eyes 13 and are hinged by pintles 14 to vertical pins 15, removably arranged in vertical sockets or openings 1G of a horizontal strip 17, extending longitudinally of and secured to the exterior of the bolster at one of the side faces thereof. The vertical sockets correspond in number with the opposite bearing recesses 7 of the sides of the bolster, and the pins 15, which have fiat upper portions, are rounded to lit the sockets and form pivots for enabling the supporting plates to be readily swung around from their supporting position to permit the pivoted chocking devices to swing downward. rllhe supporting plates or members extend beneath the upper portions of the chocking devices and receive the horizontal shoulders ll, as clearly illustrated in Figs. l and 3 of the drawing, and they are locked in such position by means of hooks lila, arranged in series and mounted on the exterior of the bolster at the side tace opposite that at which the strip 17 is arranged. The bills of the hooks engage pertorations 1S of the proximate ends of the supporting plates or members, and the shanks of the hooks are provided with eyes 19, which are linked into suitable eyes 2O or" the bolster. rThe hookeng'aged ends oit the supporting plates project beyond the bolster, and when it is desired to unload a wagon, the hook, which extends through the supporting plate or member and projecting slightly below the lower face of the same, is knocked upward out of engagement with the supporting plate or member, and the latter is swung horizontally away from the chocking member, which swings downward and releases the load..

rJ'he chocking devices may be almost instantly released to enable a wagon to be quickly unloaded.

When loading a wagon, the skid is placed against the end of the bolsterand the farther chocking device is arranged in operative position, the proximate chocking device being arranged within the bolster out of the path of the logs. fitter t-he load has been placed on the wagon, the chocking devices at the side where the waOon has been loaded, are swung upward into engagement with the load and are supported in such position by the transverse plates or members.

The bolster is provided at the bottom ot the longitudinal space or ways with longitudinal supporting strips 2l, extending outwardly from the central bearing block 3 and terminating short ot the` end spacingblock 4 to form cleaning openings 22. The strips, which are preferably constructed ot wood to render the bolster as light as possible, are arranged to support the chocking' devices, so that they may be readily grasped by the operator. The openings 22 enable any pieces or' bark, chips, and other accumulation to be readily raked or scraped out of the longitudinal spaces or ways to prevent such accumulation from interfering with the chocking devices. The outer ends Q3 ot the supporting strips are beveled to facilitate the removal of the bark and chips, and the bolster is provided above the openings 22 with transverse supporting pins 24C, arranged to receive the chocking devices when the latter are at the limit of their outward adjust-ment. The pins prevent the chocking devices from dropping downwardly into the openings beyond the reach of the operator. The strip 17, which is provided with the sockets, is preferably constructed of wood in order to avoid materially increasing the weight oi2 the bolster. tance into the sockets, and the bearing recesses 7 of the sides of the bolster are ot sui'licient depth to prevent any liability of the chocking devices and their support-ing means from becoming lost unless the wagon should upset.

Having thus fully described my invention, what l claim as new and desire to secure by Letters Patent, is

l. rl`ho combination ot bolster having spaced side portions forming a longitudinal opening and provided at intervals with bearings, a chocking device provided with a pivot adapted to be arranged in the said bearings, whereby the chocking device may be adjusted along the bolster, and a support arranged in the opening ot the bolster and located below the said bearings for limiting the downward movement ot the chocking device to hold the same within reach in any adjustment ot' the said device.
